Design of the embedded remote monitor system for building automation system based on the VxWorks

The embedded Building Automation System(BAS) is introduced in this paper, which includes BAS overall architecture, hardware and software structure. The BAS based on Pc104 bus adopts VxWorks system which is powerful real-time operating system. AMD processor is used as the BAS main controller's CPU. Meanwhile the whole information flow of the BAS is also discussed in this article. Data process and algorithm are presented in detail. Finally, the field experiments which include autonomous control mission are conducted to demonstrate the reliability and feasibility of the embedded BAS.
